They are easy to grow but you must first know how to start them. There are several ways.

You can plant onions, shallots, leeks, chives, and Siberian onions from seed. Garlic, on the other hand, does not produce fertile seed so you must plant garlic cloves. Seeds should be started inside about 10 weeks before transplanting outdoors.

I don’t have the patience for starting alliums from seed so I buy sets or dormant plant bundles which can be planted directly outside and show visible, daily growth. Sets are dried, half-grown or baby onions. If growing onions, shallots, or leeks, you can grow them from semi-dried or dormant plants that come in bundles of about 50 or 60 plants. If kept cool and dry, you have up to one week before they need to be planted. You can also buy live transplants, but this is likely more expensive than sets or dormant plants. Continue reading
